As technology moves forward, data entry and processing has also been transformed. An RFID solution has made it easy for retailers, warehouse and inventory managers, and even hospitals to enter and process the data with ease and comfort. RFID is helping every business and organization in many ways, either its data entry and processing or security of the critical infrastructures. This functioning of this system seems to be simple and easy, but a lot is going on behind the scene. Different components and elements make an RFID system that we see working proficiently.
The basic components of the RFID system are discussed below.
- RFID Tags
The RFID tags are tracking systems that identify items with the use of smart barcodes and through radio frequency technology. It has a microchip with the information of the object being identified and tagged. These tags contain partial or complete information about the items identified and scanned. All the process of identifying the item, scanning, collecting, and storing the information takes place automatically without any human input.
- RFID Readers
As a major component of the RFID solution system, RFID readers are there to collect the scanned data from the tags. Readers can either be stationary or mobile depending upon your requirements and demands. The static readers are usually used to collect data from moving tags, such as the objects moved from one place to another. The mobile tags are usually of a smaller size and can be held in hand to collect data from the tags. They are most useful to scan and collect data from the tags in warehouses and retail business.
Antennas are present in both the RFID tags and readers. These antennas help them to communicate and exchange information with each other. Antennas have different read ranges depending upon their shapes and sizes. This range is determined by the shape of the reader antennas and the size of the tag antennas.
The shapes of the antennas are linear and circular and the sizes also differ. The linear antennas send signals parallel to a single surface, either horizontal or vertical. The circular antennas are capable of sending electromagnetic waves across two surfaces. The read areas of circular antennas can be of corkscrew or helix pattern. Meanwhile, the larger antennas of RFID tags can send and receive stronger signals to and from a greater distance, and smaller antennas do the opposite.
- RFID Software
An RFID solution isn’t complete without software that processes the data. There are three types of RFID software such as firmware, middleware, and application software. Firmware is software present in an RFID device and is responsible to run that device. The middleware collects the raw data and shares it with the application software. The application software then processes this data and is used to manage inventory and/or employees.
